To all whom it may concern. I I

Be it known that I, DAVID I citizen of the United States, resident ofHadform of my anti-creeper,

donfield, Camden county, State ofNew Jersey, have invented certain newand useful Im rovements in Anticree in Devicesfor Rallroad-Rails, ofwhich t e %ollowing is a full, clear, and exact description, referencebeing had to the accompanying drawings, of "WhiCh v v Figure 1- is aplan view ofthe preferred ready to be applied to the base of a rail.Fig. 2 is a section of a rail showing my anti-creeping device as a pliedthereto, the dotted'lines showing t e position prior to clamping the endthereof over against the rail base.

Fig. 6ig. 5. Fig. 7 is a section through a modified form of cross bar of myanti-creeper. Fig. 8 is a section similar to Fig. 7, of a secondmodification. Fig. 9 shows a bar from which a number of my anti-creepersmay be out out and bent into shape.

This invention relates to anti-creeping devices for railroad rails thatis, devices for preventing the creeping or forward motion of a railroadrail in the direction of travel of the I trains moving thereover.

The object of my invention is to produce a simple and efiicient means tothis end.

The invention consists in applying to a rail an anti-creeping deviceformed of a single piece of metal, having adjacent one end thereof adownwardly extending lug to engage the side of a railroad tie, a floorportion or bar extending beneath the rail base, and

provided at one end with an inwardly turned arm closely grasping thebase of the rail between it' and said cross bar, and having, at itsopposite end, a lug or arm-which, when the parts are in final position,also grasps, be tween it and said cross bar, the opposite edge of thebase of the rail; the latter arm or lug being held in contact with thesaid base flan e by the spring pressure-of the cross bar; the atterhaving, before being applied to the rail, been so-bent that when it 1sapplied to the rail the tendency to return to the original VAUGHAN,

consists of a cross bar, 4,

bent position will cause a frictional bite on therail-base between thecross bar and said lugs orarms. e 1 is aniordinary T-rail supported uponthe usual ties, 2. The anti-creeping device, 3, one end of which isturned upwardly and over lug, 5, between which and the upper surface ofsaid bar, 4, one edgeof thebase or 'foot, 1*, of the rail is adapted toclosely fit.

Turned downwar y from the bar, 4, adj a cent one end thereof, (in thisinstance, the end having the lug or arm, 5) is-an arm or lug, 6. Theopposite end of the cross bar, 4, 1s rovided -with an upwardly extendingarm or ug, 7, corresponding with the lug or arm, 5, but it is not bentinto engagement with the rail flange except when the anti-creepingdevice has been secured in place, as hereinafter described. The crossbar, 4-, would ordinarily be bent downwardly, asin Fig. 5., or, asillustrated in Fig. 4, slightly twisted downwardly, and in applying theanti-cree ing device to the rail, after havingengage the opposite edgeof the foot flange with the lug or arm, 5, the end of the cross bar, 4-,carryin thelug or arm, 7, is, by a suitable tool, force upwardlyagainst" foot flange, and while being held in such p0 sition against thetendency to spring back to the twisted or bent position, the lug or arm,7, is swaged down tightly against the edge of the foot flange, 1*, ofthe rail, thus firmly securing the anti-cree ing device to'the rail.

As the downward y extendin lug, 6, is at one end only of the device w enit 'abuts a horizontal plane of the anti-creeper, thereby causing thediagonallyopposite corners of the arms Sand 7 to bite into and grasp therail under any strain "that may be 'put upon said downwardly extendinglug. But ifthe lug, .6, should move awayout of contact with the tie; asfor instance, whenthe rail cools at night, after a hot day,andthereby'shrinks; the anti-creeper will notloosen its grip on therail, but, owing to thes ring tension herein before referred to, 'wilialways frictionally engage the rail foot flange and hold the anticreeperin a relatively fixed position with relation to the rail.

against the tie, there is a tendency to cant in to form anarm or I theunder side of the rail rail prior to the elevation over of the arm, 7.In this formof const'r uc; tion, before applying to the''b'asefofjtherail,

from a point approximately 'under the center of the rail, and inthe formof construction illustrated Figs. 1, 2,3, and l, the bar is twisteddownwardly.

I have found it desirable to makethe device pf tempered steel to givethe spring action to the.-bar, ing the lug, 7, would preferably be leftuntempered, or malleable, so thatit might be realdily swaged overagainst the base of the rai Although I have shown in Figs. 1 to 6inclusive, my anti creeper rectangular in cross section, I may useelther of the two forms illustrated in Figs. 7 and 8, whose uppersurfaces are convex. When this convex surtace is brought over againstthe edges of the base of the rail the points of contact between the arms5 and 7 and the edges'of the base of the rail are substantially oppositeeach other; whereby, when the lug, 6, is pressed against the tie by thetendency of the rail to creep, the pressure coming entirelyat one end ofthe anti-creeping secure a better bite upon the base of the rail than ifthe bar were a erfectly flat bar, as in the other figures. of thedrawing, in which, when canted in a horizontal plane, the diagonallyopposite contacting corners of the arms 5 and 7 afford the bite.

I remark that my anti-creeper can be very economically made, as shown inFig. 9, being cut from a single bar of steel or iron or a width equal tothat of the cross bar and the downwardly extending lug, 6, before thislug,

. 6, is bent downwardly, and the lengths of the blanks for theanti-creepers would be equal to the cross bar before the arms, 5 and 7,are bent out of horizontal plane.

Having thus described my invention, 1
